Teorie nastolování agendy, rámcování a komunikace sociální změny na příkladu mediální kampaně za zákaz kouření v restauracích / Theory of agenda-setting, framing and communication of social change on case study of media campaign for smoking ban in restaurants

Slíž, Miroslav January 2017 (has links)
This diploma thesis presents the application of theoretical concepts of agenda- setting, media framing, public opinion, spiral of silence, social change communication and social marketing, including the specifics of public interest campaigns, on the example of research project "Changing the paradigm: Smoking in restaurants bothers people" which was conducted by the Faculty of Social Sciences, Charles University and research agency Ipsos, and following media campaign against smoking in restaurants. The concept of public opinion is introduced together with the theory of the spiral of silence. In addition, the thesis deals with the issue of influencing public opinion through the media, where theories of agenda setting and media framing are illustrated on examples connected to smoking ban in restaurants. Selected theoretical concepts are shown in a reflection of new media influence. Communication of social change is introduced together with social marketing theory and aspects of health communication. The specific process of social change is introduced from the perspective of issues management. There are two case studies describing the specific phases of the research project with the media campaign in the context of the presented theory. The importance and impact of the project on the public, media and...

The Brighton Declaration on Women and Sport : a management audit of process quality

Kluka, Darlene Ann 26 May 2009 (has links)
The development of gender mainstreaming programs and proactive work aimed at addressing the historical imbalances of women in all sectors of society have become the staple of most international meetings with a concern for human rights. From a sport perspective, a number of organizations are keeping this critical issue alive at global, regional, international and national levels through policy documents, declarations and calls for action since 1948 to 2008 with the Dead Sea call for action. The Brighton Declaration on Women and Sport signed in 1994 by 250 signatories is universally regarded as the ground-breaking work on Women and Sport. Yet, despite years of campaigning and numerous policy documents, legislation and world conferences on women and sport, a marked gender imbalance in sport still persists. Little or no qualitative evidence could be found of clear process strategies to be followed by signatories of the Brighton Declaration on how to translate strategic intent into quality management processes to attain the envisioned result of the Declaration. Successful implementation of the principles of the Brighton Declaration depends on quality internal organizational processes and standards. The research question for the study was hence formulated as: “Do signatories of the Brighton Declaration have appropriate management processes and standards in place to translate the principles of the Declaration into sustainable practice?” The study was approached from a qualitative perspective as the perceptions of signatories relative to the quality of management processes have been evaluated. A questionnaire (Cronbach’s Alpha Coefficient ∞=0.978) based on ISO 9001-2000 management standards was used as a research instrument and administered to 246 currently existing signatories of the Brighton Declaration. A response rate of 51% (n=125) was attained. Several international and regional organizations emerged as role players in women and sport. The United Nations provided leadership through conventions on human rights, Millennium Development Goals and declaring 2005 as International Year of Sport and Physical Education. The International Olympic Committee took initiative through quadrennial world conferences on women and sport since 1994. From the seminal “Women, Sport and the Challenge of Change” conference in Brighton, England in 1994, flowed three culminating results: the Brighton Declaration on Women and Sport, the International Working Group on Women and Sport and the International Strategy on Women and Sport. The Brighton Declaration signed by 250 signatories, enlarged and coordinated the global debate on women and sport as the first declaration to provide a worldwide ethical frame of reference and paradigm shift in social change for the construct of women in sport and women and sport. The issue of women and sport continuously remains on the agenda of global social change. The convening power of sport makes it a compelling tool for social change provided its potential is harnessed through sustainable management and processes. Social change necessitates an understanding of social change theories, stages of change management, the role of change agents as well as change management models. The major challenge facing women and sport groups is to translate strategic intent into measurable and replicable business process standards. Designing and institutionalizing processes and standards can be the mechanism to realize strategic intent and progress signatories through the stages of change management. Dawson’s (1994) processual model is used as a theoretical framework to conceptualize process management and to build a case for mapping business processes, managing quality of the processes, and continuously auditing processes through replicable standards. ISO 9001-2000 standards were selected as the instrument to audit quality management processes of signatories. Overall results obtained from the research questionnaire indicated an alarming ignorance of the Brighton Declaration as a benchmark of efforts to improve the position of women in sport and second an absence of management processes and standards to guide the process within signatories of the declaration. Only 2.8% of respondents indicated a process management system. Signatories have not institutionalized gender mainstreaming in a sport context. Results confirmed unequivocally H1 set for the study: the quality of management processes followed by signatories of the Brighton Declaration on Women and Sport (1994) to achieve the principles of the stated declaration is unsatisfactory. It was concluded that, in essence, the Brighton Declaration is an initiative to affect social change in the context of sport. Efforts to achieve the desired social change have to be managed and benchmarked according to change management models and processes to retain credibility and attain replicable and repeatable results. The ISO 9001-2000 is deemed a reliable instrument and framework to guide management process design, mapping, documenting, implementing, supporting, monitoring and controlling management processes. The alarming lack of management processes resulted in a significant gap between strategic intent and reality and suggests that the notion of gender mainstreaming feeds on emotion rather than replicable management processes. The Brighton Declaration as a seminal document will not impact substantially on achieving gender mainstreaming in sport as signatories have not succeeded in creating a critical mass necessary to tip the scale. Results also indicated that signatories are locked into the introductory stages of change management because of the lack of organized change. Low levels of competent leadership responsible for managing the change process results in loss of corporate memory regarding the Brighton Declaration. The study is concluded with recommendations and managerial guidelines focusing on building a critical mass, revisiting the significance of the seminal Brighton Declaration. A universal declaration on women and sport is recommended to serve as the nexus for global efforts to improve the position of women in sport. Signatories should adopt a managerial approach to the implementation of the Brighton Declaration rather than a social philanthropic awareness approach to move forward. Implications for further study center around investigating possible performance management systems in order to refine or supplement the recommended ISO 9001-2000 standards for quality management processes, longitudinally audit quality management processes at international and regional levels, and probing the possibility of formulating a universal declaration on women and sport to accelerate critical mass building in the context of women and sport. / Thesis (DPhil)--University of Pretoria, 2009. / Biokinetics, Sport and Leisure Sciences / unrestricted

An analysis of emerging forms of social organisation and agency in the aftermath of 'fast track' land reform in Zimbabwe

Murisa, Tendai January 2010 (has links)
The fast track land reform programme resulted in a fundamental reorganisation of rural relations in Zimbabwe, changing the landscape in an irreversible way with people from diverse backgrounds converging on former white-owned farms. This thesis tells the story of how the newly resettled land beneficiaries are organising themselves socially in response to various economic challenges. It makes a contribution towards understanding how redistributive land reforms and local government restructuring influence rural social organisation and agency. Furthermore the study examines local perceptions on the meanings of the „farm‟ and „land redistribution‟. An utterance by one war veteran “what used to be your farm is now our land and you are free to take your farm but leave our land” provides an alternative rendition to contestations of restitution versus a purely farm productionist discourse. The study, through an analysis of primary and secondary data, provides a fresh understanding of the social outcomes of fast track. It traces the evolution of land and agrarian reforms in post-independence Zimbabwe and the political and social economic context that led to „fast track‟. Through an analysis of field findings the thesis is able to define the dominant social groups that were resettled during fast track and the challenges they face in utilising the land. The findings show that the majority of the land beneficiaries were from the customary areas, with limited agricultural experiences. Local cooperation within informal networks and local farmer groups has been identified as one of the ways in which social reproduction is being organised. These groups are responsible for enhancing production capacity but they face a number of constraints. The study derives its theoretical foundation from the post 1980s debates on rural society dominated by Mafeje (1993, 2003), Rahmato (1991) and Mamdani (1996). The debates centred on how institutions of inclusion, authority and cooperation such as the lineage groups, local farmer groups and traditional authority remain relevant in the organisation of post-independent rural African society especially in a context of increased commoditisation of rural relations of production. Using theoretical insights derived from analysing the role of the lineage groups in the allocation of critical resources such as land and the influence of traditional authority (indirect rule) as a form of local government, the study examines how social organisation is emerging in areas where neither lineage nor traditional authority are not dominant. The thesis of rural cooperation through local groups as advanced by Rahmato (1991) and Moyo (2002) provides partial insights into the response mechanisms that land beneficiaries invoke in this instance. It is not necessarily an autonomous space of organisation but rather the state is actively involved through various functionaries including extension officers who invariably advance a very productionist approach. The state‟s monopoly through its local functionaries hides its political cooptation effect by emphasising organisation for production without questioning the manner in which that production is externally controlled through limited rights over land, the state‟s monopoly over inputs supply and markets for commodities. Whilst land reform has been driven by local participation through land occupations, local government reform has been technocratically determined through Ministerial directives. There is however little innovation in the form of local government that is being introduced. It expands the fusion of authority between elected Rural District Councils and unelected traditional authority functionaries. The forms of social organisation and agency that have emerged remain subordinated to the state with no links to other networks of rural producers‟ associations and urban civil society organisations. These developments form part of a longheld tradition within the Zimbabwean state where the legitimacy of local organisation and authority is usurped to service the interests of the state. Thus whilst land reform has to a certain extent accommodated the majority poor, the ensuing local government and agrarian reforms are more focused on limiting their participation in broader processes of political engagement around distribution and accumulation and their own governance.

Jarnail Singh Bhindranwale: A Charismatic Authority and His Ideology

Cibotti, John P 22 March 2017 (has links)
Sikh leader Jarnail Singh Bhindranwale’s militant and masculinist discourses were embraced by Punjabi Sikhs because of his presence as a charismatic authority, a concept first developed by sociologist Max Weber to understand the conditions surrounding and personal qualities of a figure which attracts followers. The rebellion he led in Punjab resulted from his radical exploitation of issues concerning the Sikh community. Religion was wielded as a tool, legitimizing Sikh violence as commanded by the Gurus. Radical interpretations of Sikh scripture and folklore were initially preached to rural, less educated crowds. While his sermons brought out their frustrations with the government, his charisma allowed him to manipulate young men, his largest demographic of supporters, into embracing violence. This study analyzes Bhindranwale from the perspective of the people that supported him. By identifying multiple social factors through which to understand Bhindranwale’s reign, this study exhibits his importance in understanding Sikhism in Modern India.

Role Theory as an informative lens for understanding the familial and political power struggles of Henry VIII and Mary I of England

Incorvia, Niki 01 January 2014 (has links)
This study aims to analyze the application of twentieth century sociologist George Mead's role theory to Henry VIII and Mary I, of Britain's Tudor Dynasty, regarding their treatment of their families during the early to mid-sixteenth century. Contemporary role theory can offer a useful lens to study sixteenth century royal family functionality through an analysis of Henry VIII and Mary I's lives as monarchs of England. Role theory can illuminate the role conflict that led to a separation between Henry and Mary as people and as sovereigns. Their roles, derived from traditional authority, set them apart as people and led them to behave in a way that would not have been true to their characters if they were not monarchs. The roles will therefore be given particular attention pertaining to family issues within a sixteenth century social, religious and political context. The findings of this study include an explanation of conflict with identity as well as a conflict with roles using transformation as the catalyst in the case of both of these monarchs. This study includes a qualitative content analysis, while also employing methods from the humanities to create a unique blend of methodology from both the social sciences and the field of history. This blend of methodology aids in creating a model to ensure further understanding of conflict analysis from a historical perspective.

Will Beauty Save the World? A historical context study of the Miss Venezuela pageant as a conceivable contributor to communication for development

de Windt, Jassir January 2019 (has links)
In recent years, old-hand development scholars, in the category of Dan Brockington, have expressed their concern over academia’s neglect of the significance of celebrities in the field. As has been the case of an outturn hereof, namely beauty pageants. In the last six decades, Venezuela has positioned itself not only as one of the world's largest exporters of oil but also as one of the leading engenderers of titleholders in international pageantry. The latter, which has resulted in Venezuelans regarding the pageant as a fundamental cultural undercurrent in their collective identity, seems to be a ceaseless manifestation in spite of the country’s worrisome current socio-economic status. Rather than adopting a condescending paradigm towards the Miss Venezuela pageant, it is precisely this vertex of ambiguity that opens the avenue for an interesting development question. After all, if celebrity beauty queens from Venezuela are deemed as part of the nation’s identity, could the pageant, in the same breath, be deemed as a contributor to communication for development? While espousing historical context as an analysing method and in pursuit of David Hulme’s Celebrity-Development nexus and Elizabeth McCall’s four strands of communication for development, this paper presents a qualitative study in which hands-on experts are given a platform. The findings show the evolution of a beauty pageant from a, nearly, nationalist device into a system that is grounded in the Millennium Development Goals and that aims to forge socially responsible beauty representatives that are competent enough to herald purposeful messages.

L’effet du changement organisationnel et social discontinu sur la clarté de l’identité collective : le rôle des comparaisons temporelles pour la reconstruction identitaire

Stawski, Melissa 08 1900 (has links)
Les changements rapides et profonds sont des plus en plus fréquents, tant dans les milieux de travail que dans la société. Ces changements rapides et profonds, nommés changements discontinus, sont connus pour être éprouvants pour le bien-être psychologique des individus. La littérature a proposé que les changements discontinus organisationnels et sociaux soient éprouvants parce qu’ils perturbent l’identité collective, qui fournit aux individus un cadre de référence dans lequel ils comprennent tant leur monde social qu’eux-mêmes. En réponse à un changement discontinu, l’identité collective souffrirait d’une baisse de clarté, où les individus se questionnent à savoir « qui ils sont » dans le contexte de leur groupe social. De récentes études confirment qu’un changement social discontinu provoque une baisse de clarté de l’identité collective. Toutefois, le lien entre les changements discontinus et la clarté d’une identité collective nécessite un soutien empirique robuste puisqu’aucune étude n’a manipulé expérimentalement un réel changement vécu par un groupe social. De plus, il reste à vérifier si la baisse du niveau de clarté de l’identité collective en réponse à un changement social discontinu est répliquée empiriquement sur le terrain. Le premier objectif de cette thèse est donc de vérifier l’effet d’un réel changement discontinu sur la clarté de l’identité collective d’un groupe social. Par ailleurs, les processus psychologiques qui déterminent comment les individus rétablissent la clarté de leur identité collective à la suite d’un changement discontinu demeurent à ce jour inconnus. La littérature en psychologie sociale soutient que deux processus de comparaisons contribuent à la construction de l’identité collective, soit les comparaisons sociales et les comparaisons temporelles. Il semblerait que les comparaisons temporelles soient plus prévalentes dans un contexte de changement discontinu, mais leur rôle pour rétablir la clarté de l’identité collective n’a pas été vérifié. Le second objectif consiste à vérifier si le fait d’effectuer des comparaisons temporelles est un processus psychologique qui rétablit la clarté de l’identité collective à la suite d’un changement discontinu. Cinq études réparties en deux articles ont été exécutées pour répondre à ces objectifs. Le premier article comble les lacunes soulevées dans la littérature en présentant un nouveau paradigme expérimental : le paradigme de groupes de travail Lego (PGTL). Ce paradigme expérimental simule un groupe de travail et expose ses membres à un réel changement discontinu, opérationnalisé en tant qu’un changement inattendu des valeurs qui orientent les objectifs de travail. Trois études testent l’hypothèse que l’introduction d’un changement discontinu causera une diminution du niveau de clarté de l’identité collective du groupe de travail. L’étude 1 simule un changement discontinu en transformant subitement les valeurs du groupe de collaboration à des valeurs de compétition. L’étude 2 réplique les résultats de l’étude 1 avec différente paire de valeurs opposées, soit l’efficience et l’innovation. La troisième étude réplique les résultats et la méthodologie de l’étude 1 avec un grand échantillon, ce qui permet de contrôler statistiquement pour la non-indépendance des observations. Les trois études confirment l’hypothèse que l’introduction d’un changement discontinu cause une diminution du niveau de clarté de l’identité collective du groupe de travail. Le deuxième article contient deux études qui se déroulent auprès d’Américains, dans le contexte du changement d’administration présidentielle en 2016. La première étude vérifie dans un premier temps si la clarté de l’identité collective est diminuée à la suite d’un changement discontinu sur le terrain (hypothèse 1). Dans un deuxième temps, une intervention utilisant des comparaisons temporelles est testée pour vérifier si elle permet de rétablir la clarté de l’identité collective (hypothèse 2a). Le degré d’efficacité de l’intervention utilisant des comparaisons temporelles est comparé à une intervention utilisant des comparaisons sociales, une intervention utilisant des comparaisons sociales et temporelles et une condition contrôle. La deuxième étude vérifie si l’intervention utilisant des comparaisons temporelles rétablit la clarté de l’identité collective au-delà de l’effet du passage du temps (hypothèse 2b) et au-delà des autres interventions. Les résultats confirment la diminution de clarté de l’identité collective à la suite de l’élection, et le rôle de comparaisons temporelles pour rétablir la clarté de l’identité collective. / Rapid and profound changes are increasingly common, both in the workplace and in society. These rapid and profound changes to social groups, called discontinuous changes, are known to have deleterious effects on the psychological well-being of individuals. Literature has proposed that discontinuous organizational and social changes are challenging because they disrupt individuals’ collective identity, which provides them with a meaningful frame of reference in which they understand their social environment and themselves. It has been proposed that during discontinuous changes, collective identity suffers from a decrease in clarity, where individuals question who they are in the context of their social group. Recent studies confirm that discontinuous social change causes a decrease in collective identity clarity. However, the link between discontinuous changes and collective identity clarity remains tentative since no study has experimentally manipulated a real experienced change in a social group. Finally, it remains to be seen whether the decrease in collective identity clarity following discontinuous social change is empirically replicated in the field. The first goal is therefore to provide robust empirical support to the proposition that discontinuous change causes a decrease of collective identity clarity, in a context of real experienced change. In addition, the psychological processes that determine how individuals restore collective identity clarity following discontinuous change remain unknown to this day. Literature in social psychology argues that there are two processes of comparison fundamental to the construction of collective identity, namely social comparisons and temporal comparisons. Temporal comparisons appear to be more prevalent in a context of discontinuous change, but their role in restoring collective identity clarity has not been verified. The second goal of this thesis is to verify whether temporal comparisons are a psychological process that restores collective identity clarity following a discontinuous change. Five studies divided into two articles were carried out to meet both goals. The first article fills the gaps raised in previous literature by presenting a new experimental paradigm: the Lego Workgroup Paradigm (LWP). This experimental paradigm simulates a work group and exposes its members to a real experienced discontinuous change, operationalized as an unexpected change in the values that guide the work objectives. Three studies test the hypothesis that the introduction of a discontinuous change will reduce levels of collective identity clarity related to the workgroup. Study 1 simulates a discontinuous change transforming the values in a sudden way from collaborative values to competition values. Study 2 replicates the results of Study 1 with different opposing values of efficiency and innovation. The third study replicates the results and methodology of Study 1 with a large sample that allows statistical control for the non-independence of observations. The three studies support the hypothesis that the introduction of a discontinuous change causes a decrease in collective identity clarity related to the work group. The second article contains two studies conducted with Americans, in the context of the change of presidential administration in 2016. The first study aims to validate whether the clarity of the collective identity is diminished as a result of a discontinuous change in a field setting (hypothesis 1). Then, an intervention using temporal comparisons is tested to verify if it restores collective identity clarity (hypothesis 2a). The degree of effectiveness of the intervention using temporal comparisons is contrasted with an intervention using social comparisons, an intervention using social and temporal comparisons and a control condition. The second study verifies whether the intervention using temporal comparisons restores collective identity clarity beyond the effect of the passage of time (hypothesis 2b), and beyond other interventions. The results confirm the decrease in collective identity clarity as a result of the election’s outcome and the role of temporal comparisons to restore the collective identity clarity.

THE THREAT OF ABLEIST ATTITUDES ON THE PERFORMANCE AND WELL-BEING OF INDIVIDUALS WITH DISABILITIES

Michael James Lotz (11812457) 19 December 2021 (has links)
<p>The dissertation includes two independent chapters which investigated the experiences of individuals with disabilities in connection with societal attitudes regarding disability. The first article is a systematized review which analyzes and synthesizes the existing literature on implicit and explicit disability attitudes across multiple domains (e.g., educational; occupational; healthcare). Chapter 1 identifies common themes across the existing literature and identifies potential predictors and buffers of negative disability attitudes. The article concludes with a call to counseling psychologists to address negative disability attitudes utilizing the roles and themes of the field. Finally, suggestions are made regarding the development and implementation of interventions to help address negative disability attitudes and the subsequent harmful effects. </p><p>The second article is an empirical study that examines factors related to the persistence intentions of individuals with disabilities to address the high attrition rates of this population within postsecondary environments. A moderated mediation model is proposed to address four hypotheses. First, I hypothesized academic self-efficacy would mediate the relationship between stereotype threat and persistence intentions. Second, coping self-efficacy would mediate the relationship between stereotype threat and persistence intentions. Third, social self-efficacy would mediate the relationship between stereotype threat and persistence intentions. Fourth, I hypothesized that endorsing a growth mindset would buffer against the negative indirect relationship between stereotype threat and persistence intentions which operate through academic self-efficacy. Data were collected from postsecondary students who identified as having one or multiple diagnosed disabilities at a large public university in the Midwest. The study results supported my first hypothesis that academic self-efficacy would significantly mediate the relationship between stereotype threat and persistence intentions. Additionally, the results revealed that high levels of perceived stereotype threat were associated with lower levels of coping self-efficacy and social self-efficacy, as the researcher anticipated. However, our second and third hypotheses were rejected due to these mediating factors not significantly influencing a participants’ intentions to persist within the academic environment. Finally, the results suggested that one’s mindset of intelligence was a positive main effect predictor of academic self-efficacy. However, contrary to our fourth hypothesis, mindset of intelligence did not significantly moderate the negative indirect relation between stereotype threat and persistence intentions that operate through academic self-efficacy.</p>

S'engager pour et dans un autre monde : ethnographie d'une initiative alternative luttant pour une transition sociale, politique et environnementale

Autin, Grégoire 02 1900 (has links)
Dans le cadre de ma thèse, je m’intéresse à Bioma, un collectif engagé dans des pratiques alternatives s’inscrivant dans une stratégie de « transition socio-écologique ». C’est là un collectif qui s’inscrit pleinement dans le mouvement environnemental mais qui en redéfinit en partie les revendications et les perspectives sans s’engager directement dans des actions contestataires. L’objectif de ma thèse est d’analyser précisément comment ces pratiques alternatives se construisent et s’articulent à d’autres actions collectives afin de comprendre de quelle(s) manière(s) l’alternatif participe à un type de changement social. Le modèle porté par l’alternatif, est un modèle de transition – qui se démarque ainsi des perspectives réformatrices et révolutionnaires de changement social. Cependant, le thème de la transition reste largement débattu, notamment concernant son contenu, sa forme, ses objectifs et sa potentielle radicalité. En étudiant précisément les tensions, contraintes et ambivalences qui sont vécues par Bioma, je reconstruis à la fois ce que peuvent être des pratiques alternatives, dans leur matérialité empirique, mais aussi la manière dont elles s’inscrivent dans un modèle spécifique de changement social par transition. L’alternatif est un type d’action qui, bien que s’inscrivant principalement dans un mouvement social – ici le mouvement environnemental –, soutient, participe et s’articule fortement à d’autres mouvements sociaux. En ce sens, il ne faut pas comprendre les stratégies et modèles de changements sociaux de manière exclusive : bien qu’inscrit avant tout dans une perspective de transition, l’alternatif participe ici en même temps à des stratégies plus contestataires d’un côté et à certaines stratégies institutionnelles de l’autre. Dans l’ordre de l’alternatif lui-même, les membres de Bioma expérimentent et préfigurent des pratiques matérielles et relationnelles qui visent à transformer les subjectivités des individus. Ces pratiques internes se déploient et sont projetées dans les relations dans lesquelles le collectif s’engage et participent ainsi à une diversification des modes – possibles comme réels – d’existence et d’engagement. Ces pratiques alternatives prennent place et construisent des espaces particuliers qui participent à une lutte d’occupation de l’espace. Finalement, la transition que Bioma propose est de type « ontologique »~: il s’agit de construire un « monde », différent bien qu’imbriqué dans le monde dominant. L’ensemble de ma thèse montre la manière dont ce monde, imparfait et toujours incomplet, est construit, expérimenté et engendre en même temps nombre de tensions et d’ambivalences que les membres de Bioma vivent au quotidien. Ma thèse s’appuie sur un terrain ethnographique de trois ans avec Bioma, un collectif engagé dans l’agriculture urbaine et la permaculture. Lors de ces trois années, je me suis engagé dans le collectif et j’ai participé à l’ensemble des activités et pratiques du groupe, j’ai effectué des entretiens, mené des conversations informelles et récolté et analysé l’ensemble des documents présents et produits par Bioma. C’est en tant que chercheur engagé que j’ai mené cette recherche. / In my thesis, I investigate Bioma, a self-managed collective involved in alternative practices that are part of a "socio-ecological transition" strategy within the environmental movement. Without engaging directly in contentious actions, Bioma contributes to a redefinition of the environmental movement's demands and perspectives. The aim of my thesis is to analyze precisely the ways alternative practices are constructed and articulated with other collective actions. This allows me to better understand how alternative initiatives can participate in a certain type of social change. Alternative practices carry a model of social transformation by transition. Thus, it is different from other perspectives of social change such as revolutionary or reformist ones. Transition, as a model of social transformation, is a highly debated topic. Its content, form, objectives and potential radicality are all subjected to controversies. By studying the tensions, constraints and ambivalences that are experienced by Bioma's activists, I explore what real alternative practices may be, in their empirical materiality, but also the ways in which they are involved in a specific model of social change by transition. In addition to being part of a main social movement, alternative practices usually support, participate and are articulated with other types of social movements. Hence, we shouldn't understand the strategies and models of social change in an exclusive manner. Alternative practices carry a perspective of transition while also participating in both contentious strategies and more institutional ones. The members of Bioma are experimenting and prefiguring material and relational practices that aim at transforming individuals' subjectivity. These internal practices unfold and are projected in the relationships that Bioma create. Therefore, this group participates to the diversification of possible and actually existing modes of existence and commitment. Through these alternative practices, Bioma builds specific spaces that are part of a spatial struggle. The type of transition for which Bioma fights is "ontological" as it aims at creating a "world" different from the dominant world, even though it is interwoven within it. My thesis shows how this always imperfect and unfinished alternative world is built and experimented. Through this analysis, we see how this world generates a number of tensions and ambivalences that the activists of Bioma live daily. My analysis draws from a three-year long ethnographic fieldwork during which I was immersed in projects of urban agriculture and permaculture. During this time, I became part of the group and I participated in every collective activities and practices. I also conducted interviews, had in-depth informal conversations and collected and analyzed the documents that were present in my fieldwork. For the whole of my fieldwork, my research posture was one of a militant ethnographer.
